Omega Protein (OME)

(a) Escrow Agents Right to Confirm Instructions. In the event funds transfer instructions are given (other than in writing at the time of execution of this Agreement), whether in writing, by
telecopier or otherwise, the Escrow Agent is authorized to seek confirmation of such instructions by telephone call back to the person or persons designated in incumbency certificates for each party delivered by the parties concurrently herewith,
and the Escrow Agent may rely upon the confirmations of anyone purporting to be the person or persons so designated. To assure accuracy of the instructions it receives, the Escrow Agent may record such call backs. If the Escrow Agent is unable to
verify the instructions, or is not satisfied with the verification it receives, it will not execute the instruction until all issues have been resolved. The persons and telephone numbers for call backs may be changed only in writing actually
received and acknowledged by the Escrow Agent. The parties agree to notify the Escrow Agent of any errors, delays or other problems within 30 calendar days after receiving notification that a transaction has been executed. If it is determined that
the transaction was delayed or erroneously executed as a result of the Escrow Agents error, the Escrow Agents sole obligation is to pay or refund such amounts as may be required by applicable law. In no event shall the Escrow Agent be
responsible for any incidental or consequential damages or expenses in connection with the instruction. Any claim for interest payable will be at the Escrow Agents published savings account rate in effect in New York, New York.
